“…In addition, due to the lighter mass of turbine blades, the working efficiency and service life of the blades are also significantly improved. 2,3 In recent years, to continuously increase the working temperature of turbine blades and improve the comprehensive performance of the engine, many scholars are studying single crystal hollow turbine blades. 4 The structural design of the hollow fan blade includes two parts, one is the aerodynamic shape and the other one is the internal cavity.…”

Blades are widely used in aerospace, navigation, new energy, and other fields. The blades with hollow structure can not only reduce the weight of the engine and centrifugal force, but also improve the working efficiency and the service life. Though the mechanical properties of blades will be improved during plastic deformation, the hollow structure may be severely destroyed. In this paper, experiments of pressing hollow blades filled with a low melting point (LMP) mandrel are designed. Experimentally, when the LMP alloy is used both as a mandrel material and as a flexible tenon for the blade, the blade can be formed accurately with a well-maintained hollow structure. In addition, the LMP alloy is used as a flexible tenon in the experiment, which can lock some degrees of blade freedom to a certain extent. After the multi-pass pressing, both the forming defect and spring back of the blade can be reduced.

“…Scholars have also conducted some research works in this direction. Cheng et al [15] argued that the traditional trial-anderror method is inefficient for complex models; Zhang et al [16] adjusted the conventional shrinkage rate and compensated along xyz three-coordinates; Jiang et al [17] proposed a dimensional compensation model based on Taylor-expansion; Zhang et al [18] proposed an optimization method based on reverse engineering. These methods ignore the structural feature of the casting, the mould still needs to be repaired.…”

“…First, all the shapes of the soft elastomer matrix where the magnetic particles are patterned are 2D planar. There is no shape of matrix based on free-form surface, which is common in industrial applications [24], including architectures, aircraft, and aerospace structures [25,26,27]. Stretchable electronics [28,29], origami designs [30,31] and bionic structures [8,9] are also in the form of free-form surfaces.…”

Ferromagnetic soft materials (FSM) can generate flexible movement and shift morphology in response to an external magnetic field. They have been engineered to design products in a variety of promising applications, such as soft robots, compliant actuators, or bionic devices, et al. By using different patterns of magnetization in the soft elastomer matrix, ferromagnetic soft matters can achieve various shape changes. Although many magnetic soft robots have been designed and fabricated, they are limited by the designers' intuition. Topology optimization (TO) is a systematically mathematical method to create innovative structures by optimizing the material layout within a design domain without relying on the designers' intuition. It can be utilized to architect ferromagnetic soft active structures. Since many of these 'soft machines' exist in the form of thinshell structures, in this paper, the extended level set method (X-LSM) and conformal mapping theory are employed to carry out topology optimization of the ferromagnetic soft actuator on man- * Address all correspondence to this author.ifolds. The objective function consists of a sub-objective function for the kinematics requirement and a sub-objective function for minimum compliance. Shape sensitivity analysis is derived using the material time derivative and adjoint variable method. Two examples, including a circular shell actuator and a flytrap structure, are studied to demonstrate the effectiveness of the proposed framework.
